That every wave length of light except purple is being absorbed by the hat. The hat will be the color purple
just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
Voltage = current * resistance
V = I*R
I = 4 A
R = 2 ohm
V = 4 A * 2 ohm
= 8 volt
It is most accurate to say that body mass index (BMI) provides information about an individual's height-weight ratio. The correct answer is B.
Answer:
P = I V power produced by source at voltage V thru resistance R
I = V / R current thru resistance R
P = V^2 / R
Power produced will decrease as the output resistance R increases
Check: if R increases to ∞ the power produced will go to zero
